Highly efficient degradation of polybutylene succinate (PBS) and polycaprolactone (PCL) by a recombinant marine fungal cutinase.

ABSTRACT: Biodegradable plastics, such as polybutylene succinate (PBS) and polycaprolactone (PCL), pose potential ecological risks due to their slow degradation rates in natural environments. Therefore, there is an urgent need to develop efficient enzymatic degradation technologies for the end-of-life management of PBS and PCL. In this study, we identified a marine fungal cutinase, AaCut10, which exhibits significant degradation activity on PBS and PCL films under mild conditions. AaCut10 can achieve degradation rates of 26.33% for PBS and 85.67% for PCL films within 20 min at 37°C, corresponding to degradation efficiencies of 315.96  kg PBS·(mol AaCut10·h)⁻¹ and 1028.04  kg PCL·(mol AaCut10·h)⁻¹, respectively. Notably, AaCut10 showed even higher degradation effici
